Referring to fig. 1 and 4, a cooking appliance according to an embodiment of the present application is an electric pressure cooker, which includes a cover 1 and a pot body 2, wherein the cover 1 covers the pot body 2. The pot body 2 comprises an inner pot 21 and a pot body for accommodating the inner pot 21, and the pot body also comprises a base (not numbered) for supporting the pot body, a heat preservation cover 22, a shell 23 annularly sleeved on the base, a cover plate 24 covering the shell 23 and a heating device (not shown). The inner pot 21 is accommodated in the heat-preserving cover 22, and the cover plate 24, the outer shell 23 and the base together form a cavity for accommodating the heat-preserving cover 22.

The inner pot 21 and the heat-insulating cover 22 may be made of stainless steel. The heating device can adopt a traditional heating plate or an electromagnetic coil plate and is arranged between the bottom of the inner pot 21 and the bottom of the heat-preserving cover 22 to heat the inner pot 21. When the pressure cooker is used, a closed cooking cavity is formed between the inner pot 21 and the pot cover 1 so as to perform pressure cooking. The top edge of the heat-insulating cover 22 is provided with pot body pot teeth 220, the cover body 1 is provided with pot cover pot teeth 10, and the pot cover pot teeth 10 and the pot body pot teeth 220 are mutually locked, so that the pot cover 1 is locked on the pot body 2 during cooking. The cooker cover 1 is also provided with a pressure limiting valve 11, after cooking is finished, the pressure limiting valve 11 is opened to exhaust air, so that the temperature and the pressure in the cooking cavity can be quickly reduced, and the cover can be opened quickly and safely.

The pot cover 1 and the pot body 2 of the cooking appliance adopt a split structure, and the pot cover 1 can be completely taken down from the pot body 2. As shown in fig. 5, the cover plate 24 is provided with a sliding seat 240 at the rear side of the top thereof, and the sliding seat 240 is provided with a sliding groove 241; the rear side of the pot cover 1 is provided with a mounting seat 12, the bottom of the mounting seat 12 is protruded with a sliding part 120, and the sliding part 120 is inserted into the sliding groove 241 and slides in the sliding groove 241. The sliding groove 241 is arc-shaped, and two sides of the sliding groove are provided with blocking surfaces for blocking the sliding part 120 from excessively rotating. Through the cooperation of the sliding part 120 and the sliding groove 241, the pot cover 1 can rotate relative to the pot body 2 to form a locking position and an opening position. In the open position, a user can hold the handle 13 arranged on the top of the pot cover 1 to lift the pot cover 1; in the locking position, the lid teeth 10 and the lid teeth 220 are locked with each other, and the lid 1 cannot be opened.

After the pot cover similar to the split electric pressure cooker in the prior art is lifted, the pot cover is generally required to be additionally placed on a table board, and the table board is easily polluted and a user is easily scalded in the taking and placing process. This application cooking utensil has the front side of convenient operation and keeps away from the rear side of front side, cooking utensil has set up slot 25 on this pot body 2, and this slot 25 sets up the slope rear side (right back or left back promptly) of the pot body 2 and extend along upper and lower direction. The rear side edge of the pot cover 1 is provided with a bolt 15, and the bolt 15 extends outwards from the edge of the pot cover 1 in a horizontal state; referring to fig. 7, after the pot cover 1 is separated from the pot body 2, the bolt 15 is inserted into the insertion groove 25, so that the pot cover 1 is fixed on the inclined rear side of the pot body 2, and thus, when a user inserts the pot cover 1 into the insertion groove 25, the user does not need to stretch his arms to the rear side of the pot body 2, and when the user takes food, the user does not easily touch the pot cover 1 with his hands.

As an embodiment of the present application, referring to fig. 5, the insertion groove 25 is provided on the cover plate 24 and formed on the sliding seat 240. In order to simultaneously consider the part of users who are used to operate with left hands, the cover plate 24 is provided with two slots 25 which are respectively and symmetrically arranged. The two insertion grooves 25 are located at both ends of the sliding seat 240 and at both ends of the sliding groove 241. The cooker cover 1 is correspondingly provided with two left and right bolts 15, and the right slot 25 is convenient for a user to operate with the right hand; the left slot 25 may facilitate left-handed operation by a user.

As mentioned above, the lid can rotate with respect to the body between a locked position and an open position, in this embodiment, when the lid 1 is in the open position, the latch 15 is not aligned with the corresponding slot 25 of the body 2. However, as an improvement, the latch 15 may be disposed at a proper position of the pot cover 1, so that when the pot cover 1 is located at the open position, the latch 15 is aligned with the corresponding slot 25 of the pot body 2, which is more convenient for a user to insert and place the pot cover 1.

It can be understood that the inner pan handles 210 are disposed on two sides of the inner pan 21 for facilitating the taking of the inner pan, and the two slots 25 are respectively close to the corresponding inner pan handles 21, but do not affect the taking of the inner pan 21 from the inner end of the pan body 2. Therefore, the user can conveniently insert the pot cover 1 without influencing the taking and placing of the inner pot 21. Referring to fig. 8, in order to make the lid 1 tilt and stand backwards on the pot body 2, the slot 25 has a slight tilt angle, for example, gradually tilts outwards from bottom to top, so that after the bolt 15 of the lid 1 is inserted and fixed, the lid 1 is placed in a state of tilting outwards, so that the upper space of the inner pot 21 can be avoided, and the lid 1 is not easily touched and scalded when taking or placing food or the inner pot 21. The specific design is based on the fact that the inner pot 21 can be taken out normally, namely, the pot cover 1 placed at the rear side of the pot body 2 cannot influence the taking out of the inner pot 21. Alternatively, the slot 25 may be vertically arranged, and the latch 15 may be designed to be inclined outward and upward, so that the lid 1 may be inclined backward when inserted into the slot 25.

In addition, a detachable water storage box 243 (see fig. 2) is further installed below the sliding seat 240, the water storage box 243 is located right below the sliding chute 241, and a water leakage hole 244 is formed in the bottom wall of the sliding chute 241. When in use, the condensed water dropping on the sliding seat 240 along the edge of the pot cover 1 will flow into the sliding groove 241 and then flow into the water storage box 243 through the water leakage hole 244. Therefore, the chute 241 may be referred to as a water chute 241.

The slot 25 can be a through slot, and the size of the corresponding bolt 15 can be designed to be longer, so that the pot cover 1 is more reliably fixed. The cross-sectional dimension of the bolt 15 is substantially the same as the cross-sectional dimension of the slot 25, and after the bolt 15 is inserted into the slot 25, almost no gap exists, so that the pot cover 1 can be prevented from shaking.

In addition, the insertion groove 25 is located outside the water guide groove 241 and formed by recessing downward from the surface of the sliding seat 240, and the top surface thereof is the surface of the sliding seat 240, so that the top surface of the insertion groove 25 is higher than the water guide groove 241, thereby preventing water from flowing into the insertion groove 25.

Referring to fig. 3 and 4 in combination with fig. 6, the pot lid 1 includes an upper lid 16 and a lower lid 17, the upper lid 16 is made of plastic material by injection molding, the lower lid 17 is made of stainless steel, and the peripheral edge of the lower lid is formed with the pot lid teeth 10 extending inward. The mount 12 and the plug 15 are integrally formed by the upper cover 16. The sliding part 120 of the mounting base 12 protrudes downwards from the bottom surface of the pot cover 1; the bolt 15 is designed to be hollow and is provided with a cavity, and a reinforcing rib 150 is further arranged in the cavity. As described above, the cooking appliance is further provided with the opening stop mechanism 14, and the opening stop mechanism 14 is provided at the edge of the lower cover 17 and protrudes outward. The sliding seat 240 of the pot body 2 is provided with a groove (not shown), the opening stopping mechanism 14 is clamped in the groove to prevent the pot cover 1 from rotating relative to the pot body 2, and the phenomenon that a user is scalded due to food overflow caused by high air pressure when the cooking appliance is opened during working is avoided. The bottom of the lower cover 17 is also provided with conventional structures such as an anti-blocking cover and the like, which are not described one by one.

Referring to fig. 5, the upper cap 16 includes a main body cap 160 and a detachable cap 161, the main body cap 160 is substantially annular, and has an opening (not numbered) formed through a top wall thereof at a middle portion thereof, and the detachable cap 161 is snap-fitted at the opening. When cooking is completed, the removable cover 161 may be removed to expose the lower cover 17, i.e., the top wall of the cooking chamber, to help dissipate heat from the cooking chamber. Cold towels or ice bags and the like can be placed in the opening 114, so that the cooking cavity can be helped to dissipate heat quickly, and the requirement of a user on eating as soon as possible is met.

As an embodiment of the present application, a front side edge of the detachable cover 161 is formed with a wrench portion 162, and the wrench portion 162 is disposed to be tilted up with respect to a main plane of the detachable cover 113 for tilting up the detachable cover 161 with a finger. When the user uses the portable heat sink, the wrench 162 is pulled upward by a finger to easily remove the detachable cover 161 from the main body cover 160 for rapid heat dissipation.

The two sides of the pot body 2 are also provided with a pair of handles 26, which is convenient for a user to carry the cooking utensil, the sliding seat 240 basically occupies the whole space between the handles 26, the strength can be improved, and the pot cover 1 can be effectively supported. The front side of the pan body 2 is also provided with a display device 27 for the customer to perform cooking procedure operations.

This application cooking utensil is through having set up slot 25 in this pot body 2 outsides, and the 15 slopes of the bolt of pot cover 1 of can being convenient for are inserted backward and are put to can prevent that pot cover 1 from placing the in-process scald user, also can prevent simultaneously that the user from being scalded by the pot cover when getting flourishing food.

Referring to fig. 9, in the present embodiment, the center lines of the bolt 15 and the slot 25 are both disposed in the tangential direction of the pot cover 1 or the pot body 2, and the center point is a tangent point. Here, a line connecting the center of the pot body 2 and the center point of the slot 25 is defined as a line a; the center line of the slot 25 in the tangential direction is defined as line B.

As mentioned above, when the lid 1 is inserted into the pot body 2, it is necessary to prevent the lid 1 from affecting the normal taking and placing of the inner pot 21. In this regard, the present application further improves upon the aforementioned cooking appliance. One of the solutions is to slightly twist the lid 1 relative to the original state of fixing it to the pot body 2, so that the front side of the lid 1 moves backward again, and the back side can lean forward, and it is only necessary that the front side of the lid 1 leaves the position of the inner pot handle 210 backward. This can be achieved by two means, one by adjusting the position of the slot 25 and the other by adjusting the shape of the pin 15.

Referring to fig. 9, according to an embodiment of the present application, the slot 25 'has a certain width in the circumferential direction, and lines a and B are marked in the drawing, wherein line B is the center line of the slot 25' before rotation. Taking the slot 25 'on the right side as an example, the slot 25' rotates counterclockwise around its own center by a certain angle, so that the front side (251 ') of the slot in the circumferential direction is farther from the center of the pot body than the rear side (252'). The bolt 15 is kept unchanged and is still horizontally arranged along the tangential direction of the pot cover, and when the bolt 15 is turned upwards from the horizontal direction to be vertically placed by taking the central point of the bolt 15 as a rotating point, the distances from the front side and the rear side of the bolt 15 to the center of the pot body 2 are consistent. Therefore, in order to insert the right latch 15 into the right slot 25', the front side of the lid needs to be turned backwards by a certain angle, and the back side of the lid needs to be turned forwards (in fact, the front side of the lid turns anticlockwise around the center point of the latch 15), so that the front side of the lid moves backwards, thereby preventing the problem that the user can easily touch the lid with his hand during the operation of the front side.

It can be understood that, in design, the slot 25 ' on the left side is rotated clockwise around its own center by a certain angle, so that the front side (251 ') in the circumferential direction is farther away from the center of the pot body than the rear side (252 ').

Referring to fig. 10 and 11, similar to the previous embodiment, but the present embodiment adjusts the pin 15, and the slot 25 remains unchanged and is still arranged in the tangential direction of the pot body. Lines a and B are also marked in the drawing. When the pot cover is horizontally placed, the bolt 15 'has a certain width along the circumferential direction, and the front side 151' in the circumferential direction is lower than the rear side (152 ') thereof, i.e. the bolt 15' is obliquely arranged on the side of the pot cover, and the oblique angle is 10 degrees in the embodiment. That is, when the lid is turned upwards by using the center of the latch 15 'as a rotation point, the front side 151' of the latch 15 'is closer to the center of the lid than the rear side 152' when the lid is turned from the horizontal state to the vertical state. The lid is now parallel to line B in figure 11.

The distance between the front and rear sides of the slot 25 and the center of the pot body is consistent, so that in order to insert the bolt 15 'into the slot 25, the front side of the pot cover needs to be deflected backwards by a certain angle, and the rear side of the pot cover needs to be deflected forwards (actually, the bolt rotates anticlockwise around the central point of the bolt 15'), so that the front side of the pot cover moves backwards, and the problem that a user can easily touch the front side of the pot cover by hands when operating the front side can be prevented. The dotted line in fig. 11 shows the right bolt 25, which is also understood to be the final position of the right bolt 15'.

In addition to twisting the lid, there is another solution in which the lid can be translated backwards relative to the pan body. Referring to fig. 12 and 13, according to an embodiment of the present invention, the latch 45 is disposed on the front side of the lid, and the center line of the latch 45 is located on the front side of the center of the lid, and line C in the drawing is the boundary line of the front and rear sides of the lid, wherein line C is aligned with the center point of the slot 25. The center line of the latch 45 is line D, which is understood to be an assembly line running through the connection point of the lid and the body, which assembly line does not run through the center of the lid, but is located near the front side.

Compared with the manner in the first embodiment, the latch 15 and the slot 25 are both arranged along the tangential direction, so in this case, the assembly line of the latch 15 and the slot 25 is the center line C of the lid. However, in the present embodiment, since the latch 45 is not provided along a tangent line but is provided on the front side, the situation is different. Taking the right side latch 45 inserted into the right side slot 25 as an example, the line C of the center line of the pot cover is at the left rear of the line D of the assembly line of the right side latch, and in order to insert the right side latch 45 into the right side slot 25, the whole pot cover needs to be moved along the line B to the left rear, that is, the line D is moved to the original position of the line C, that is, the intersection point of the line B and the line D is the center point of the slot 25. The cover is closer to the rear side of the pot body, and the front side of the cover is also moved backward and leftward, thereby preventing the user from easily touching the cover with his hands when operating the cover at the front side. Here, as can be seen in conjunction with the previous fig. 10, the position of the lid in fig. 10 is close to the state before the movement. In theory, the slot 25 may also be moved in the same manner, but moving the slot 25 to the rear side causes some inconvenience in use for the user.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the scope of protection of the present application.
